Answer:
Answer:
(-12, 12) D
Step-by-step explanation:
Substitute y = 12 into the first equation:-
12 = -3/4x + 3
-3/4 x = 12 - 3 = 9
x = 9 * -4/3
= -12
so the answer is (-12, 12)
Step-by-step explanation:
The solution to the system of equations is (20, –12).
The correct option is (A)
Equations are mathematical statements containing two algebraic expressions on both sides of an 'equal to (=)' sign. It shows the relationship of equality between the expression written on the left side with the expression written on the right side.
There are different parts of an equation which include coefficients, variables, operators, constants, terms, expressions, and an equal to sign. When we write an equation, it is mandatory to have an "=" sign, and terms on both sides.
Given:
y = -3/4 x +3 and y=-12
So,
-12= -3/4 x + 3
-12-3 = -3/4 x
-15= -3/4 x
x= -15* -4/3
x= -5* (-4)
x= 20
Hence, the solution is (20, –12).
